I run an absurd amount of roulettes daily, and 80% of the tanks I end up with in light party content use Provoke and Ultimatum as a pull or just after it. So whether or not the OP intended for this to apply also to light party duties, it's a thing in light party duties. And a lot of the time, the people wasting Provoke/Ultimatum on pull are the same ones who lose aggro to Scatter spam, but still won't listen to explanations of basic enmity generation.
